Purpose:

  1. Preliminary look at hi/lo multivariate contrast (cross-validated euclidean) in each task.
  2. Preliminary qualitative comparison of effects of prewhitening and pattern standardization on multivariate contrast.

Notes on analyses:

Target TRs:

Contrasts (cross-validated euclidean):

Normalizations:

Plotting and statistical details:

2 Network-level

Estimates are first averaged across parcels within network per subject. Group-level stats and plots are then displayed at the network-level.

2.1 curves

2.1.1 beta contrasts

2.1.2 t-stats on contrast

3 parcel-level

3.1 curves

3.1.1 counts of significant effects per TR

3.1.2 DMCC55B ROIs

3.1.3 largest 20 ROIs

3.2 maps (target TRs)

Unthresholded and thresholded t-statistics displayed on inflated brains. Threshold at fdr-corrected p-value (across all parcels) of 0.05. Note: colors are reverse-scaled, i.e., dark == strong effect, light == weak effect (so strong effects show up on white background).
